01 Relationship analysis

The graph workspace: typed nodes, source-rated edges, paths you can audit.

Build the picture of who connects to whom across people, organizations, locations, events, and other public-source entities — with confirmed and suspected edges visible at a glance.

Selection drives the entire workspace. Pick a node and the map, timeline, and inspector follow.

Force-directed, hierarchical, and circular layouts
Path tracing with min source-rating filters and edge-level evidence inspection
Source reliability (A–F) and credibility (1–6) on every claim

02 Geospatial workspace

Where activity happens — areas, tracks, geofences.

The map is a working layer of the investigation. Spatial queries drive review areas, vessel and movement tracks, port-call clusters, and event heatmaps.

Selection follows the same entity that's active in the graph and timeline. One thread across three views.

From query to typed entities, with the source passage attached.

Hybrid BM25 + vector retrieval surfaces source-rated documents. Named-entity extraction proposes people, organizations, locations, events, and other public-source elements with the exact passage they came from.

The analyst confirms the merge before it sticks. Proposed edges remain marked suspected until reviewed.

Workspace-scoped retrieval — context never leaves the investigation

Key judgement

It is probable PROBABLE · 55–80% that Sample Org A LLC and Sample Org B Ltd. are operating as a single beneficial-ownership structure controlled by Entity A-1042¹, with Event E-203 representing one observation in a recurring pattern within the sample dataset².

Confidence basis

Two corroborating A/1 sample sources³, one B/2 trade-press sample⁴. Lower-rated indicators excluded from the central claim.

Sample registry filing lists Entity A-1042 as registered party; Sample Org A appears as nominee on the same record. Synthetic.

Open questions

Observation gap Apr 11–14 for Vessel V-021. Additional nominees beyond Sample Org A.

04 Report & evidence chain

Source-linked briefs with a designed evidence trail.

Draft the brief from the workspace. Every claim carries its source pointer and its place in the evidence chain. Confidence uses a calibrated vocabulary so reviewers can challenge a number, not a vibe.

Designed to preserve provenance from raw source to final export, and to support analyst review before finalization.

Drag-and-drop sections with footnoted claims
Designed to maintain an append-only evidence trail on artifacts

Why it matters

Connected evidence beats stitched-together tools.

Public-source investigations break when claims drift away from the sources that supported them. Sentra is built so they don't.

One canvas

Three views, one selection.

Graph, map, and timeline pulse to the same entity. Analysts hold a single thread instead of rebuilding context across tabs.

Provenance preserved

Every claim points back to its source.

Designed to preserve provenance — source span, reliability rating, evidence hash — through extraction, analysis, and export.

Built for review

AI proposes, the analyst decides.

Merges, edges, claims, and briefs surface as proposals. Sentra supports analyst review before finalization.

Responsible use

Security direction.

The product surfaces are shaped so AI assists, humans decide, and every output can be traced back to its source.

Public-source focusDesigned around public information, with workspace-scoped storage and explicit out-of-scope guardrails.Inputs and outputs stay within the workspace boundary.
Analyst-in-loopNo silent finalization of merges, edges, claims, or briefs.Supports analyst review before finalization.
ProvenanceEvery claim resolves to the source span it came from, with reliability (A–F) and credibility (1–6) attached.Designed to preserve provenance through to export.
Audit trailDesigned to maintain an append-only evidence trail on artifacts, with a structured audit log on operator actions.For workspace integrity and reviewability.

Honest framingCosint does not currently claim compliance certifications, customers, funding, partnerships, or cloud-provider endorsement. The items above describe design direction the product is actively building toward.
